SAMUEL W. KLASS, Q WAU'KESHA, WISCONSIN, ASSIGNOB/ TQ ARTHUR, W. F. KLASS, OF VJAUKESI-IA, NI$COLNSIN- EGG-TESTING DEVICE.

Application filed July 5, 1913.

To all 20740 211, it may concern lie it lmown that l, SAMUEL W. Ki'nss, a citizen oi the United States, residing at ll aulresha, county of lVaukcsha and State of i i isconsin, have invented new and useful in:provements in Egg-Testing Dovlces, oi which the following is a specification.

My invention relates to improvements in egg testing devices.

The object of my invention is to provide an testing device or apparatus adapted to be used for testing incubator eggs, in which an tray may be taken from the incubator with the thereon, placed in the tester and all the in the tray speedily tested and the tray returned to the incubator withrmt disturbing or turning the eggs, other than those found to be defective.

in the drawings l igurc 1 is a plan view of a testing device embodying my invention. 2 is a sectional view drawn on line sc-w of Fig. 1. Fig. 3 is a sectional view drawn on line y i of Fig. 1.

Like parts are identified by the same reforence characters throughout the save 'al views.

A cabinet, open at the top, is provided with a ledge B adapted to receive an egg tray C of any ordinary type, such as are used in incubators. The cabinet may be in the form of a simple box open at the top, or it may comprise a set of telescoping members A. and A, each in the form of a box open at the top and at one end, the member than the member A, and adapted to slide within the member A .t'rom front to rear, as shown. The rear end of the member A is open and the front end of the member A. is open, so that trays C of differing lengths may be mounted in the member A upon the ledge B and project rearwardly t irough the open end of the member A into abutting contact with a partit-ion wall D near the rear end of the member A.

A lamp ld, preferably an electric lamp, is mounted upon a bar F which projects through a slot G in the wall of the cabinet, whereby the bar F may be manipulated from the exterior and the lamp E adjusted to any desired position in the space H between the bottom of the cabinet and the egg tray. The bottom of one of the members A or A, (preferably the member A), is provided with slots l. Bolts ll: project downwardly Specification of letters Patent.

through the bottom walls oi the members A and A, and the bottom of the member A may also be provided with slots or holes to receive these bolts. The bolts K are required to clamp the members together in any desired position of adjustment, clamping thumb nuts L being employed for this purpose.

In use the members A and A will be adjusted to form a cabinet of the proper size to receive the egg trays of any given incu bator. The thumb nuts L will then be turned to clamping position, after which an egg tray may be taken from the incubator, placed in the cabinet upon the ledges B, and the lamp E moved along the rows of eggs underneath the same, the several being inspected by the operator from above as the light passes underneath them. Eggs found. to be defective will be removed and placed in the compartment M between the wall D and. the rear end of the member A. If dc sired, the detective eggs may be classified asinfertile and bad eggs, those of one class being placed in the compartment M and those of the other in the compartment H, until the inspection is completed. As soon as the inspection is completed, the tray will be removed and placed in the incubator and another tray substituted therefor in the test in g device.

I attach great importance to the fact that my device is adapted to receive egg trays from an incubator without disturbing the eggs in the trays. It is well known that the germ of an egg will float or move from one position to another when the egg is disturbed. After a period of rest, the germ rises to the upper portion of the egg and in this position, inspection can be easily made from above with a light underneath the egg and the rays thereof directed through it to the eye of the observer. My improved apparatus, therefore, permits all the eggs in a tray to be quickly and rapidly inspected since all eggs containing live germs will have the germs exposed in the most favorable position to be detected by the observer. By forming the device in such a manner that it is expansible to receive trays of diiiering sizes, my device is adapted to be used in connection with any incubator, and since the walls of the device, when properly adjusted, will be in close proximity to the several margins of the tray, the rays of light will -vided with a source of illumination, said cabinet being of proper size and shape to receive egg trays from an incubator.

2. An egg testing device comprising a cabinet provided with interior tray receiving ledges and slotted below said ledges, a bar extending through said slot and provided with a source of illumination, said cabinet being of proper size and shape to receive egg trays from an incubator, and said cabinet being also formed in movable sections adapted to be adjusted upon each other to increase or diminish the dimensions of the cabinet to accommodate trays of differing sizes.

3. An egg testlng device comprising an expansible cabinet having interior ledges adapted to receive and support incubator egg trays of difierent size, said cabinet having side Walls sliding upon each other, and cooperating with the end walls to inclose an egg tray when the cabinet is in either an expanded or contracted position, and means within the cabinet for illuminating the eggs in such egg trays from the under side.

4. An egg testing device comprising a cabinet provided with interiortray receiving ledges and slotted below said ledges, a bar extending through said slot and provided with a source of illumination, said cabinet being of proper size and shape to receive egg trays from an incubator, said cabinet being subdivided by partition walls into storage compartments for eggs removed from the trays.

In testimony whereof I aflix my signature in the presence of two witnesses.
